Description:
http/wpt/service-workers/cache-control-request.html
http/wpt/service-workers/about-blank-iframe.html

The first failure that I saw on the dashboard was on 4/9/2022 at 249475@main for http/wpt/service-workers/cache-control-request.html and 4/19/2022 at 249770@main for http/wpt/service-workers/about-blank-iframe.html.  Both tests have been flaky for their entire history on the dashboard.  They are flaky failures on iOS Release x86_64.
